The 2014 Bolder Boulder starts at 30th and Walnut and winds through Boulder neighborhoods with live music and entertainment at every corner. The race finishes at the University of Colorado’s Folsom Field.

Olympic marathoners Ryan Hall, Shalane Flanagan and Deena Kastor will highlight the elite field at the 2014 Bolder Boulder.

The race’s biggest change to the elite field will be the American teams: Separated now into Team Red, Team White and Team Blue, for both women and men, in a nod to the Memorial Day event Monday.

Flanagan and Hall both raced in the Boston Marathon in April. Flanagan, the 10,000-meter bronze medalist in the Beijing Olympics, posted the fastest time on the course ever by an American woman, breaking her personal best by several minutes. She finished seventh.

Hall finished 20th in 2:17:50 in Boston, but was widely credited with racing that ultimately helped Meb Kefelzighi win the race, the first American to do so since 1983.

On Wednesday, Bolder Boulder officials announced the 18 teams of professional men and women from across the globe who will be racing in the 2014 Bolder Boulder International Team Challenge, which was created in 1998 with three-person teams in a team-by-country format. The men’s and women’s professional races follow the Bolder Boulder course and are scheduled to finish in a packed stadium at the University of Colorado’s Folsom Field before a Memorial Day tribute.

“We are excited to welcome so many top-level American athletes in this year’s International Team Challenge as well as fast international teams that race well at altitude,” said Bolder Boulder race director Cliff Bosley in a statement. “Historically, teams that train at altitude preform very well at the Bolder Boulder, and we think it will be a very exciting and competitive men’s and women’s race with this year’s lineup.”

The International Team Challenge will take place at the Bolder Boulder on Monday, with the women’s race beginning at 11:15 a.m. and the men’s race beginning at 11:26 a.m.
